I detta examensarbete har möjligheten att kvalitetssäkra en monteringsbana vid Parker Hannifin Manufacturing Sweden AB:s anläggning i Trollhättan utretts. Syftet med studien var att förbättra kvalitetssäkringen vid Fasta Motorers F11-montering och arbetet baserades på en tidigare utarbetad felläges- och effektanalys. För att styrka kundperspektivet genomfördes en undersökning av vad kunderna reklamerar, i form av PQP-anmälningar samt NCMR-rapporter. Genom att därefter identifiera kritiska monteringsmoment i felläges- och effektanalysen, PQP-anmälningar och NCMR-rapporter, var en prioritering möjlig att utföra. Prioriteringen resulterade i att feltyperna felvridet lagerhus, felplock av material samt kuggfel ansågs vara de mest kritiska att kvalitetssäkra. Målet med arbetet var att reducera det totala risktalsvärdet, vilket var möjligt genom en konceptgenerering samt ett konceptval för de specifika prioriteringarna. I samband med konceptgenereringen undersöktes, genom intervjuer med berörd personal, specifika kundbehov. Dessa kundbehov omarbetades därefter till målspecifikationer för att underlätta genereringen av koncept. Då informativa koncept var framtagna återstod ett val av det bäst lämpade konceptet. Valet utfördes med två olika metoder, screening och scoring samt 3P, för att ytterligare säkerställa att rätt koncept valts. Det var därmed möjligt att uppdatera felläges- och effektanalysen med de valda åtgärderna och då påvisa att syftet var uppnått. Syftet med kvalitetssäkringen uppnåddes genom att sänka det totala risktalsvärdet med 47,5 procent mot det tidigare risktalsvärdet, 6415. / In this thesis an investigation has been made in order to find possibilities to assure the quality at an assembly line at Parker Hannifin Manufacturing Sweden AB:s facility in Trollhättan. The purpose with the study was to improve the quality assurance at Fixed Motors F11-assembly line, where the work was based on an already conducted process-FMEA. In order to verify and further investigate the customer perspective, an inquiry was also done to see what customers complained about, this with help of PQP, Product Quality Problems, and NCMR, Nonconformance reports. By analyzing the process-FMEA, PQP and NCMR reports an identification and prioritization of critical failures were made. The result from these steps was three failures, incorrect positioning of the bearing house, picking of incorrect material and incorrect gear timing. These three were considered to be the most critical failures to quality assure. The aim with the quality work were set to reduce the total RPN, Risk Priority Number, of the process-FMEA, which was rendered by applying a concept generation and a concept selection for the specific failures. In relation with the concept selection, interviews were made with staff that was considered important and vital for the project. This was made to identify specific customer needs regarding solutions to the three failures. From these needs a target specification was developed to ease the generation of concepts. After generating a number of well specified concepts, a concept selection was made using the two methods screening and scoring and an additional Parker method called 3P to further establish that the right concepts was chosen. Further it was then possible to update the process-FMEA with the chosen concept solutions and by doing that reaching the project aim. By implementing the solutions it was possible to reduce total RPN, 6415, with 47,5 percent.

In this increasingly competitive scenario, it is highlighted that the companies have to organize themselves to develop products in an efficient, fast and proper manner in the first time. The Failure Mode and Effects Analysis (FMEA) has to be conducted to determine potential risks and evaluate them in relation to its relevance, probability of occurrence and possibility of detection. These risks have to be minimized by introducing preventive actions, considering that the FMEA is an important tool for defects prevention in products. Therefore, the objective of this study is to present the introduction of a more efficient and effective method to perform the FMEA report, proposing improvement actions to speed up its preparation, thus reducing development time and eliminating deviation of interpretation, because for different cross-functional teams, different interpretations in the index of severity, occurrence and detection have been diagnosed for the same products and / or similar applications. As a result, this work adopted the methodology of action research. Based on this study it was suggested a FMEA standardized by process, where all manufacturing processes existing in the studied organization were identified and mapped. This standardization provided a significant time reduction to perform the FMEA from six to two meetings with the cross-functional team and also allowed quick, efficient and systemic feedback looping, consequently gaining productivity and reliability in the product development process as result. / Devido à forte influência da globalização, pesquisadores e empresários reconheceram a necessidade e a importância do desenvolvimento de novas abordagens para aumentar a vantagem competitiva no desenvolvimento de novos produtos. Nesse cenário cada vez mais competitivo, é evidenciada a necessidade de que as empresas se organizem para desenvolver produtos de forma eficiente, rápida e correta pela primeira vez. A análise do modo e efeitos de falha (Failure Mode and Effects Analysis) deve ser conduzida para a determinação de possíveis riscos e avaliada com relação à sua relevância, probabilidade de ocorrência e possibilidade de detectá-los. Estes riscos devem ser minimizados através da implementação de ações preventivas, tendo em vista que o FMEA é um importante instrumento para prevenção de defeitos em produtos. Para isso, o objetivo desse estudo é propor a introdução de um método mais eficiente e eficaz na elaboração do FMEA de processos, propondo ações de melhorias para agilizar sua elaboração, reduzindo o tempo de elaboração e eliminando, assim, divergências de interpretação, pois para diferentes equipes multifuncionais, diferentes interpretações nos índices de severidade, ocorrência e detecção eram diagnosticadas para os mesmos produtos e/ou aplicações similares. Para tanto, nesse trabalho foi adotada a metodologia de pesquisa-ação. Baseado nesse estudo foi sugerido um FMEA padronizado por processo, onde foram identificados e mapeados todos os processos de manufatura existentes na organização estudada. Essa padronização propiciou uma sensível redução no tempo de elaboração do FMEA de seis para duas reuniões com a equipe multifuncional e também permitiu uma rápida e eficiente retroalimentação de maneira sistêmica, ganhando produtividade e confiabilidade no processo de desenvolvimento de produtos.

Mundialmente, eventos relatados constituídos por incidentes e acidentes em radioterapia, tem aumentado ao longo dos últimos 25 anos e a maioria destes eventos são resultados de falha humana, além de terem ocorrido com maior frequência em centros sofisticados que utilizam alta tecnologia. Em radioterapia a Gestão da Qualidade necessita de uma abordagem prospectiva através de análise de risco. Esta abordagem é defendida por recentes publicações por ser atualmente uma urgência em virtude do expressivo número de acidentes ocorridos. Dada a complexidade do processo em radioterapia, a busca pela qualidade do tratamento de forma a garantir a segurança do paciente é um dos assuntos mais discutidos mundialmente. Embora apenas 14% dos centros de radioterapia no Brasil ofereçam tratamentos com a técnica de radiocirurgia intracranial (SRS), estudos relativos a qualidade do tratamento relacionada a segurança do paciente submetido à esta técnica, é de relevante importância, pois qualquer desvio da dose prescrita é considerado muito mais crítico que em outras modalidades de tratamento radioterápico, já que são utilizadas altas doses de radiação que em geral variam de 10 Gy a 40 Gy para lesões até 50 mm de diâmetro, que são aplicadas em uma única fração ou até cinco frações. Tendo em vista tais conhecimentos, o objetivo deste trabalho foi atender um novo paradigma de Gestão da Qualidade, através do desenvolvimento de um modelo de análise de risco e de um Índice de Qualidade para a SRS no Brasil, a partir da técnica de Mapa do Processo e FMEA utilizadas pelo TG 100/AAPM. O trabalho foi desenvolvido em três centros de radioterapia de referência em alta tecnologia, dois localizados no Rio de Janeiro e um em São Paulo. Um Mapa do Processo de SRS foi identificado em cada centro de radioterapia e em seguida foi aplicada a técnica FMEA para todos os subprocessos identificados no mapa. A partir dos valores de NPR obtidos pela FMEA foi realizado um ranqueamento dos modos de falha. Modos de falha com NPR ≥ 100 e S ≥ 7 foram escolhidos como prioridade para implementação de estratégias de segurança. A partir das pontuações do parâmetro S atribuídas na aplicação da FMEA foi criado o Índice de Severidade (IS) e um Índice de Qualidade (IQ) foi criado a partir de uma relação entre o NPR e o IS. O resultado deste estudo, indica que as estratégias de segurança sejam implementadas para os 10 primeiros modos de falha do ranking e uma reavaliação do processo deve ocorrer a cada 1 ano. É também indicado que o IQ obtenha uma melhora mínima de 9% após a reavaliação do processo. De forma geral, o estudo mostrou que a adoção da ferramenta FMEA juntamente com o IQ são de fato justificadas, por minimizar os riscos para o paciente, melhorando a qualidade do tratamento aprimorando a segurança, criando mecanismos que permitam a garantia de que a dose será entregue de forma precisa e exata, e consequentemente, aumentando as chances de cura ou do controle local com uma desejada qualidade de vida para estes pacientes. / The reported events in radiotherapy that constitute accidents or incidents have increased worldwide in the last 25 years. Most of these events resulted from human failure and have happened in radiotherapy centers that use high technologies. The radiotherapy Quality Management needs a prospective approach through risk analysis. This approach is supported by recent publications as this actually extremely needed due the large number of accidents. Because of the complexity of the process in radiotherapy, the search for quality of care in order to ensure patient safety is one of the most discussed topics worldwide. Although only 14% of radiotherapy centers in Brazil offer treatments with intracranial radiosurgery technique (SRS), studies about the quality of care related to the safety of patients undergoing this technique is of great importance. Any deviations from the prescribed dose using SRS technique is considered more critical than in other methods of radiation treatment, as the delivered doses in SRS are higher, in the range of 10 Gy to 40 Gy, to lesions up to 50 mm in diameter, which are delivered in a single fraction or in five fractions. In view of those information, this work aims to satisfy the new Quality Management paradigm by developing a risk analysis model, and a Quality Index for SRS in Brazil, through the techniques of Process Map and FMEA used in the TG100/AAPM. The study was performed in three high technology reference radiotherapy centers, two located in Rio de Janeiro city and one in Sao Paulo city. A SRS Process Map was identified for each radiotherapy center, and then FMEA technique was applied in every subprocesses identified on the map. From NPR values obtained by the FMEA a ranking of failure modes was held. Failure modes with NPR ≥ 100 and S ≥ 7 were chosen as priority to implement safety strategies. From the scores assigned to the S parameter in the implementation of FMEA a Severity Index (SI) and a Quality Index (QI) were created from an association between the NPR and the SI. The result of this study indicates that safety strategies should be implemented for the first 10 failure modes of the ranking, and a new evaluation of the process should occur every year. In addition, it is also indicated that the QI shows a minimum improvement of 9 % after the re-evaluation of the process. Overall, the study showed that the adoption of the FMEA tool together with the QI are justified as they minimize the risks to the patient, improving the quality of care and enhancing the safety Taken together the FMEA and the QI create mechanisms for ensuring that the dose will be delivered more precisely and accurately, and consequently, this increases the chances of cure or local control of the tumor, improving quality of life of the patients.

Les véhicules autonomes, tels que les drones, sont utilisés dans différents domaines d'application pour exécuter des missions simples ou complexes. D’un côté, ils opèrent généralement dans des conditions environnementales incertaines, pouvant conduire à des conséquences désastreuses pour l'humain et l'environnement. Il est donc nécessaire de surveiller continuellement l’état de santé du système afin de pouvoir détecter et localiser les défaillances, et prendre la décision en temps réel. Cette décision doit maximiser les capacités à répondre aux objectifs de la mission, tout en maintenant les exigences de sécurité. D’un autre côté, ils sont amenés à exécuter des tâches avec des demandes de calcul important sous contraintes de performance. Il est donc nécessaire de penser aux accélérateurs matériels dédiés pour décharger le processeur et répondre aux exigences de la rapidité de calcul.C’est ce que nous cherchons à démontrer dans cette thèse à double objectif. Le premier objectif consiste à définir un modèle pour l’état de santé et la décision. Pour cela, nous utilisons les réseaux Bayésiens, qui sont des modèles graphiques probabilistes efficaces pour le diagnostic et la décision sous incertitude. Nous avons proposé un modèle générique en nous basant sur une analyse de défaillance de type FMEA (Analyse des Modes de Défaillance et de leurs Effets). Cette analyse prend en compte les différentes observations sur les capteurs moniteurs et contextes d’apparition des erreurs. Le deuxième objectif était la conception et la réalisation d’accélérateurs matériels des réseaux Bayésiens d’une manière générale et plus particulièrement de nos modèles d’état de santé et de décision. N’ayant pas d’outil pour l’implémentation embarqué du calcul par réseaux Bayésiens, nous proposons tout un atelier logiciel, allant d’un réseau Bayésien graphique ou textuel jusqu’à la génération du bitstream prêt pour l’implémentation logicielle ou matérielle sur FPGA. Finalement, nous testons et validons nos implémentations sur la ZedBoard de Xilinx, incorporant un processeur ARM Cortex-A9 et un FPGA. / Autonomous vehicles, such as drones, are used in different application areas to perform simple or complex missions. On one hand, they generally operate in uncertain environmental conditions, which can lead to disastrous consequences for humans and the environment. Therefore, it is necessary to continuously monitor the health of the system in order to detect and locate failures and to be able to make the decision in real time. This decision must maximize the ability to meet the mission objectives while maintaining the security requirements. On the other hand, they are required to perform tasks with large computation demands and performance requirements. Therefore, it is necessary to think of dedicated hardware accelerators to unload the processor and to meet the requirements of a computational speed-up.This is what we tried to demonstrate in this dual objective thesis. The first objective is to define a model for the health management and decision making. To this end, we used Bayesian networks, which are efficient probabilistic graphical models for diagnosis and decision-making under uncertainty. We propose a generic model based on an FMEA (Failure Modes and Effects Analysis). This analysis takes into account the different observations on the monitors and the appearance contexts. The second objective is the design and realization of hardware accelerators for Bayesian networks in general and more particularly for our models of health management and decision-making. Having no tool for the embedded implementation of computation by Bayesian networks, we propose a software workbench covering graphical or textual Bayesian networks up to the generation of the bitstream ready for the software or hardware implementation on FPGA. Finally, we test and validate our implementations on the Xilinx ZedBoard, incorporating an ARM Cortex-A9 processor and an FPGA.

Este trabalho apresenta uma abordagem da ferramenta FMEA, Failure modes and effect analysis, em uma integração com os custos relativos à qualidade, aplicada ao processo de soldagem GMAW, gas metal arc welding. O objetivo principal é evidenciar a importância da utilização desta ferramenta para se prever e prevenir falhas de processo antes que as mesmas ocorram, e minorar os custos da qualidade envolvidos. A proatividade da ferramenta FMEA proporciona, através das ações recomendadas de melhoria, a possibilidade de se mensurar com antecipação os custos relativos à prevenção, avaliação e falhas de qualidade. O método empregado para esta abordagem foi de uma pesquisa-ação, sendo estabelecida uma equipe multidisciplinar para implantação e execução da FMEA e avaliação dos custos da qualidade. Os resultados obtidos na fase anterior à aplicação da FMEA informavam que os custos das falhas apresentavam uma participação de 89,84% dos custos da qualidade; com a utilização da ferramenta, estes foram reduzidos para 3,82% devido ao investimento de melhoria. Objetivando-se equilibrar os custos associados, foi projetada uma estimativa futura de 50% de custo de falhas. Na análise comparativa dos custos da qualidade, foi verificado que os custos de falhas relativos à fase anterior ao FMEA reduziram 86% em relação à projeção futura, e os custos da qualidade reduziram de 74%, evidenciando-se deste modo o benefício da utilização da ferramenta FMEA para a redução de custos operacionais. / This paper presents an approach of the FMEA tool, Failure modes and effect analysis, in integration with the costs of quality, applied to the GMAW welding process, gas metal arc welding. The main objective is to highlight the importance of using this tool to predict and prevent process failures before they occur, and reduce the costs of quality involved. The proactivity of FMEA tool, provides through the recommended actions for improvement, the possibility to measure in advance the costs of prevention, assessment and quality failures. The method employed for this approach was an action research, which established a multidisciplinary team for deployment and implementation of FMEA and evaluation of quality costs. The results obtained in the previous phase to the implementation of FMEA reported that the cost of failure had a 89.84% share of the costs of quality; using the tool, these were reduced to 3.82% due to improved investment. In order to balance the costs, was projected a 50% estimated future cost of failures. In comparative cost analysis we founded that the quality failure costs related to the phase prior to FMEA reduced 86% compared to the projected future, and quality costs were reduced of 74%, demonstrating thereby the benefit of using the FMEA tool to reduce operating costs.

Implementation of common and sustainable working methods is highly valued for Scania IM.The aim of their maintenance work is to increase availability to enable production targets. Themaintenance work should be safe with regard to human and environment, cost-effective andbased on suitable maintenance strategies. In order to achieve this, a common standardized workprocess is required for how Scania IM will work in the preparation phase of the components.The purpose of this degree project was to investigate how a new workflow can be used todevelop appropriate maintenance and stock strategies for components. The work was delimitedto analyze eighteen components, distributed over nine different subsystems in a multi-operationmachine.The project began with a meeting on Scania IM where the work process and the research objectwere presented. Relevant literature was selected and the selected research object was dividedinto different subsystems. Based on these subsystems, components were selected to beinvestigated. The work process was divided into two parts, process for maintenance strategyand process for stock strategy. In order to determine the appropriate maintenance strategy forthe components, interviews were applied. Interviewers were selected according to the technicalarea of the specific component. The stock strategy process was not complete as it was missinga systematic approach. This approach was subsequently developed into a new, expanded workprocess according to the preferences of the company. Afterwards, appropriate stock strategieswere selected through data collection and interviews.All components were assigned storage and maintenance strategies based on the characteristicsof each component, i.e. probability of failure, consequences of failure and lead time.Developing an appropriate maintenance strategy, which corresponds to the first part, turned outto be easier than determining the appropriate stock strategy. However, it turned out that the firstpart had an unclear decision point - to determine if failure modes occurred regularly or not.There was no definition of the concept of regular failures, which may have contributed to nocomponent being assigned predetermined maintenance as a strategy. Therefore, this isrecommended to be done in order for the process to be useful and correct.This degree project shows that the new work process can be used to develop appropriatemaintenance and storage strategies, provided that the person using the process has sufficientknowledge in the subject. The work process is meant to be used by maintenance staff, and musttherefore be verified before it can be established as a standardized working method. / Implementering av gemensamma och hållbara arbetssätt är en värdegrund hos Scanias IM.Målsättningen med underhållsarbetet är att öka driftsäkerheten för att möjliggöra uppsattaproduktionsmål. Underhållsarbetet som bedrivs ska vara säkert med hänsyn tagen till människaoch miljö, kostnadseffektivt och baserat på väl avvägda underhållsstrategier. För att uppnå dettaså krävs det bland annat en gemensam standardiserad arbetsprocess för hur Scania IM skallarbeta vid underhållsberedning av maskinkomponenter. Syftet med detta examensarbete var attundersöka hur en ny arbetsprocess för underhållsberedning kan användas för att ta framlämpliga underhålls- och lagerstrategier för maskinkomponenter. Arbetet avgränsades till attanalysera arton komponenter, fördelade över nio olika delsystem i en fleroperationsmaskin.Projektet inleddes med ett möte på Scania IM där arbetsprocessen samt undersökningsobjektetpresenterades. Relevant litteratur valdes ut och det valda undersökningsobjektet delades upp iolika delsystem. Utifrån dessa delsystem valdes komponenter ut som skulle undersökas.Arbetsprocessen var uppdelad i två delar, process för underhållsstrategi samt process förlagerstrategi. För att bestämma lämplig underhållsstrategi för komponenterna tillämpadesintervjuer. Intervjupersonerna valdes ut efter vilket teknikområde den specifika komponententillhörde. Processen för lagerstrategi var inte fullständig då den saknade ett systematiskttillvägagångssätt. Detta tillvägagångssätt utvecklades efterhand till en ny, utökad arbetsprocessi enlighet med verksamhetens önskemål. Därefter valdes lämpliga lagerstrategier ut genomdatainsamling och intervjuer.Samtliga komponenter tilldelades lager- och underhållsstrategier som baserades påförutsättningarna hos varje komponent, det vill säga felsannolikhet, konsekvens och ledtid. Attta fram lämplig underhållsstrategi, som motsvarar första delen, visade sig vara enklare än attbestämma lämplig lagerstrategi. Det visade sig dock att den första delen hade en otydligbeslutspunkt - att ta ställning till om feltyper uppstod regelbundet eller inte. Det fanns ingenanpassad definition av begreppet regelbundna fel, vilket kan ha bidragit till att ingen komponenttilldelades förutbestämt underhåll som strategi. Därför rekommenderas detta att göras för attprocessen ska bli användarvänlig och korrekt.Detta examensarbete visar att den nya arbetsprocessen går att använda för att ta fram lämpligaunderhålls- och lagerstrategier, förutsatt att den som använder processen har tillräckligakunskaper inom området. Arbetsprocessen är tänkt att användas av underhållsberedare, ochmåste därför verifieras av sådana innan den kan etableras som en standardiserad arbetsmetod.
